VAPORIZING-DOME.

T0 all/whom t may concern.' l

Beit known that VI, JESSE D. LANGDON, acitizen of the United States, residing at Waterville, in the county vof Douglas and State of Washington, have invented certain vnew and useful Improvements in Vaporiz-V ing-Domes; and I do .herebydeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in thek art towhich it appel-,

theprovision of Ya device of this characterV whereby several ofthe various products of crude oil may 'be used as fuel'to produce a gas for the engine. J 1 "y vAnother object of the invention is the provision (of a v'aporizer. disposed in averticalposition and formed witha circuitous gas passage through it,'said Yvaporizer being provided exteriorly with a water jacket through'which is designed to circulate hot water designed to materially assist in the vaporization of the fuel as it passes through the device. 1 Y

A further object of the invention is to arrange the water jacket of the vaporizing dome in circuit withthe watercooling system of 'the engine and to provide means whereby the water circulation throughl the vaporizing dome maybe controlled at will. A stillrfurther object of the invention isl the provision-of means whereby the Vhot water and steam may be admitted from the vaporizing dome water jacket into the circu-itous gas passage within the dome for mixture with the hydrocarbon in its passage therethrough.

Vith these and other objects in view as will appear as' the description proceeds, the invention comprises the various-.novel features of construction, combination and arrangement of parts as will be more fully described hereinafter, and set forth with par-y ticularity in the appended claims.

Similar characters of reference are used to denote like parts throughout the accompanying drawings and the, following descriptlon. 1 Referring more particularly to the drawings, the reference numeral 1 indicates an inner cylindrical casing which is designed to form an inner hydrocarbon chamber. The upper end of this cylindrical casing is rounded or dome shaped as indicated by the numeral 2', for a purpose which will presently appear.

This inner casing 1 is surrounded by an outer -cylindrical casing 3 whichv is arranged in spaced relation to it and-is also providedk with a rounded upper or domeshaped end 4 arranlged' in spaced rela-tion `to the dome The lower ends of the inner and outer casings land 3' respectively are connected together, and in this Ainstance to form an yintegral structure, by a suitably designed bottom.v Y

Extending upwardly andcentrally through the bottom isa vertically. disposed hydrocarbon Vintake pipe 6 which extends upwardly to a point below and adjacent the dome 2 of the inner casing. The lower end of this intake'pipe 6 extends downwardly below the bottom 5 a suitable distance and terminates, if desired, in an angular extension 7 which is providedwith an attaching flange' 8, whereby the intake pipe may be connected to a suitable carbureter indicated by the numeral 9. Y

In the preferred form of myinvention the v'aporizing dome proper is shown formed into and an integral part of the intake mani,- fold 10 of'theinternal combustionengine. As shown the dome in` this instance is dis posed intermediate the opposite exhaust ends 11 of themanifold 10 and slightlypto one side ythereof as, clearly shown in Figs. 2 and 3 of the drawings, The Iintake manifold 10 is attached'tothe .vaporizing dome as indicatedVbyV-the numeral 12-to` the intake manifold, so that any hydrocarbon, water or steam that may exist upon the bottom can be readily and freely sucked into theintake manifold by the suction caused by theopera tion ofthe engine. v The space between the inner and outer casings `1 and 3 respectively is designed for the reception of water` which is admitted to it from the water outlet manifold 13 through the dome 4 of the outer casing through theV medium of a pipe 14. This pipe 14 has one end tapped as :at '15 into the water outlet manifold 13, and'it is to be understood that this end 15 ofthe-pipe 14 `may betappedl. into the water outlet manifold in any place lfound desirable and best suited for the purpose in-i tended. The oppositeend of the pipe 14 'is suitably. attached toa plug 16 that is threadedly connected' through the central portion ofthe 'dome 4 of the outer casing and is held in vposition through the medium of a lock nutV or other suitable fastening means, 17 I Y The 'outer casing 3 is provided adjacent its lower end with a water outlet pipe 18 that V.is tapped through the casing as indicated at19. Arranged withinthis outlet pipe 18 isa suitable controlling valve or cock 2O that isv provided with an actuating handle or lever 21 whereby the cock may be opened or closed as desired. From the outer casing, the water outlet pipe 18 leads around the motorfin this Yinstance and istapped into the water-inlet manifold 22 adjacent its up-- Y In the operation of the device, and we will 4say for instance it is desired to use gasolene for a fuel for the motor, the mixing4 valve 2,5 is'closed and thelvalve 2'0 opened so that a complete circulation'of hot water will pass through the vaporizing dome between the inner and outer casing, this water being in.

' ,trodu'cted into the top of the vaporizing dome Vfrom the water' outlet manifold, and preferably'from the hottest point, and is then discharged vthrough the' water outlet fpipe 18 into'the water inlet manifold of the engine. t By this arrangement thefvaporizing dome will be keptsufliciently heatedto vproduce an efficient vaporizingy medium.

When/the motor is started'vthe gas*` is sucked in throughV the intake pipey 6 `and is lshot upwardly Y'against Athe inner,A heated dome2 wherev it is further vaporized and manifold 10 of the lmotor, and thence on 70 into the motor.

Y When itis desired tol-use heavier hydro; carbony such as kerosene, the Icock `,2O Ais 1 opened Vtopermit of afreecirculation of hot 'water through the v'aporizing dome. In

order to make ahighly;combustiblegas out` of kerosene,` it is necessary to mix certain amount of wateror steam with it to produce, athorough volatilization of. it, kand in order toxa'ccomplish this, fuse. the mixing valve 25' to control "admission of anydesired amount of water vorsteam intoA the'.inner` hydrocarbon chamberfwhereit will be readfv ily mixed with the fuel in its passage to the` motor. In .this instance when the motor 'is started the kerosene gas or vapor is sucked in Athrough the intake f pipe" 6y .and shot. against the inner superhcatedI dome 2 where it is further vaporized Vand then allowed to descend bythe force of gravity between Vthe intake pipe 6 and the innerv casing 1 Vand then mixed Ywith the water o riys'team that is admitted into the innerhydrocarbon cham-p. ber through themixingvalve 25, after'whieh it passes out through the opening 29,0f theY intake manifold 10`into the engined It isY to be understood, however, that the mixing valve 2 5may. be used to admit water or=steam or both intoV the innerfhydrocarbon Y mixing chamber of the dome andfmixed 190 withany kind of fuel thatfisybeing used to l It'isfals'orto. be noted that V l this mixing'valve can be actuated to advanan advantage.

tage to pre-ventv preignition of the gas'rwhen it reaches the engine. f 1 7 i 195 From the foregoingdescription it will be 'apparent-` that through lthe medium ofthe hot water jacketedrvaporizing dome provided with its circuitous'passage .vertically disposed, that any :hydrocarbon Vproduct 110 may be used as a fuel to run theengine in an eflicient mannerand with-a greatly, increased amount of power due to the complete vaporization of thehydrocarbon gas in its passage through the Vvaporizing dome. 1,15

While I .have shown the vaporizing dome as-Yhereinbefore*described Aformed intoV and i an integral part of the intake manifold of v the engine, vI desirer to have it understood. that if found desirable, the lvaporizing dome may be made separate and detachablycon`- t nected inany suitable vmanner to the intake manifold. Inorder to better illustrate this,

and by' referencefto Fig. 4, it will bef seen that l have provided-the vaporizing dome 125 adjacent v its lower. end with a. lateral' extension 30.*provided: with an outlet ,opening-31 which communicates with the inner hydrocarbon mixing chamber. Theouterend of this extension 30 is providedfwith angularr 11,30

flanges 32 to which is attached Vthe angular ange 33 of the intake manifold lateral extension 34, through the medium of suitable bolts or other suitable fastening means 35. The intake manifold extension 34: is formed integral with the intake manifold 36.

What I claim is 1. A vaporizing device embodying an elongated casing having a lateral outlet port near one end, a hydrocarbon inlet pipe extending through said end of the casing past said port to a point near the opposite end of the casing, a water jacket surrounding said casing and having a water inlet and a water outlet, and means for establishing and controlling the flow of water from Said jacket into said casing.

2; A. vaporizing apparatus comprising a vertical elongated casing having a lateral outlet port near its lower end, a hydrocarbon inlet pipe extending upwardly through the lower end of said casing past said port to a point near the upper end of the casing, a water jacket surrounding said casing and having a hot water inlet at its upper end above the casing and a water outlet near its lower end, and means for establishing and controlling the flow of water from the lower end of the water jacket into the lower end of the casing.

3. A vaporizingl device comprising a vertical elongated casing having a lateral outlet port near its lowerl end and an inclined portion below said port extending upwardly from the lower end of said casing, a hydrocarbon inlet pipe extending l upy wardly through the lower end of said casing Atwo subscribing witnesses.
